Pivot to Pump Control System

Slide_Pivot

Many center pivot irrigation systems are installed on land that is undulating and pumps are obviously selected to meet the highest required operating system pressure. At times during the irrigation cycle the location of the pivot on the irrigated land may result in less than the maximum system operating pressure being required however pumps are rarely designed to regulate pressure. The P2P (Pivot to Pump) control system offers and affordable solution to optimize the pumps use of energy by automatically regulating the speed of the pumps motor based on the actual real time system pressure requirements.

How the system works.
During the center pivots operation, the pressure at the end of the center pivot is compared to the pressure at the center of the pivot. If the the actual Pump_Panels_02system pressure is deemed to be too low at either of the measured points, instruction is sent to the pump station to increase the pressure needs. Inversely, if pressure is deemed to be too high, instruction is sent to the pump station to lower the system pressure. By automatically adjusting the pumps pressure energy is saved and the pump is always being utilized optimally. the actual d if pressure is constantly.

The system makes use of an intelligent controller located at the center of the pivot and linked to a pressure sensor installed at the center and a second pressure sensor installed at the end of the pivot. A similar controller is installed at the pump station and interfaced with a variable speed drive (preferably a Senlan VSD motor control panel) and also linked to a pressure sensor installed on the supply pipeline at the pump station. The two controllers are linked with a wired or wireless (wifi or similar network) communications link allowing for real time data to be exchanged between them.
